The present patent application claims priority to U.S. Provisional Application No. 61/081,880, filed on Jul. 18, 2008 by the same inventor, the contents of which are incorporated by reference as though fully set forth herein.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to protection for tools or parts such as tools for cleaning windows.

2. Description of the Related Art

A squeegee is a tool edged with a blade which is capable of removing water from a window. There are many different types of squeegees which are made by many different manufacturers. Several types of squeegees are disclosed in U.S. Pat. Nos. 911,194, 948,631, 1,628,783, 1,706,053 1,840,023, 2,103,198, 2,207,651, 2,261,475, 2,307,460, 2,440,099, 3,013,290, 3,787,921, 3,950,813, 4,611,363, 4,716,616, 5,175,902, 5,321,868, 5,381,581, 5,611,108, 5,628,086, 5,630,246, 5,809,605, 5,930,863, 5,946,762, as well as U.S. Design Pat. No. D388,568, the contents of all of which are incorporated by reference as though fully set forth herein. Manufacturers that make squeegees include Unger International, Inc. of Bridgeport, Conn., Sorbo Products of Palm Desert, Calif. and Ettore Products Company of Alameda, Calif.

One problem with squeegees, however, is that they have a tendency to undesirably scratch the window, or the film or tint on the window. Another problem with squeegees is that the blade can undesirably bunch up, which makes it less useful to remove water from the window. Another problem with squeegees is they require the use of tension clips, which are very small and easy to lose, difficult to install, cause the blade to bunch up, and they do not hold the blade in place during use.
